Blue-green algae can irritate the skin, and swallowing large amounts of contaminated water can cause nausea, vomiting and diarrhea. People who are sensitive to smells can have respiratory irritation.

They are urging the public to take the following precautions:

  • Do not drink, swim, wade, use personal watercraft or boats in waters where there is a visible bloom
  • Keep pets and livestock away from the area
  • Eating healthy fish from the lake is safe as long as it’s been filleted. Be sure to rinse the fish, throw out the guts and cook it well
  • Do not eat shellfish in waters with algae blooms

If you see any fish kills in the area, contact the Florida Fish and Wildlife Research Institute at 1-800-636-0511.
